Nonlinear Bending Analysis of Micro/Nano Rectangular and Annular Sector Plates Using a Modified Higher-Order Shear Deformation Theory the Couple Stress

A tangent linear adjoint for a low-resolution dynamical model of the atmosphere is used to derive the optimal forcing perturbations for all state variables such that after a specified lead time the model response has a given projection, in terms of an energy norm, on the pattern associated with the 51-yr trend in the Northern Hemisphere winter tropospheric circulation, 1948/49–1998/99. A featur...

rabbitfish is economically valuable teleost species which lives in shallow coastalwaters. two species of rabbit fish have been recognized in southern sea of iran (persiangulf) as namely siganus sutor and siganus javus. in the current study, in order toinvestigate the histology of the annular ligament of the s. javus’ eye, the prepared sectionsof the eyes of twelve healthy specimens were studied...

The term "Arctic Oscillation" (AO) has recently been introduced to describe the leading structure of SLP variability over the Northern Hemisphere. A key feature of the AO is its zonally symmetric appearance, with a primary center of action over the Arctic and opposing anomalies in midlatitudes. Does the AO's annular appearance result from significant temporal correlations between SLP anomalies ...

This work proposes a small pattern and polarization diversity multi-sector annular antenna with electrical size profile of ka = 1.2 0.018λ, respectively. The is planar comprises sectors that are fed using different ports to enable digital beamforming techniques, efficiency gain up 78% 4.62 dBi,...
